Teams is up and running in our tenant but when I browse to https://teams.microsoft.com/ it redirects to https://teams.microsoft.com/undefined/_ and displays the text "Bad Request". The client is working fine and the web portal was previously working fine too.
Try another browser, I had the same issue but only in Edge, not Chrome...
The Desktop app works fine.
Yes - works fine in Chrome. Same error in IE even after deleting browser cache.
There is some redirect going on in IE to take me to https://teams.microsoft.com/undefined/_. Seems the URL https://teams.microsoft.com/_ (with an underscore at the end works) but not the plain URL.
@Barry CaruthThis is solved by using 'sudo teams'. So somewhere is a permission problem, probably with a file. Question is..... which file?
